nmh: Delete (a bit outdated) comment about locking mechanisms

Since 02 Feb 2014 (post-1.6) the default locking mechanisms are
(directly from m4/locking.m4):

 - aix*|cygwin*|linux*: fcntl
 - freebsd*|*netbsd*|openbsd*|darwin*: flock
 - everything else: dot

The original comment was probably about just NetBSD and maybe Solaris
(it's dated 1999). Solaris still uses the `dot' mechanisms by default
but we no longer have any local patches about locking.
